Abstract :
A state-of-the-art report on reversible (or lossless, or error-free, or information preserving) compression of medical images is presented. Reversible compression consists of two steps, decorrelation and coding. Methods for intraframe decorrelation of 2-D images can be divided into three classes, viz., transform, predictive, and multiresolution decorrelation. Transform decorrelation methods are found to be unsuited for reversible compression. DPCM (differential pulse code modulation) the best predictive method, decorrelates well, but has a great disadvantage in its parameter dependency.<>
